Question

The ratio of the length to the width of a picture is 5:2. The picture is enlarged so that its length is 15 inches now. What is the width of the enlarged picture?

Answer 1

Answer: The picture's dimensions will be 10"x15".

Step-by-step explanation:

Length:   4      2     10

Width:     6      3     15

You can tell because 15 isn't divisible by 6, but it is divisible by 3, which goes into 6.

Divide 6 by 2.

6/2=3

To keep the ratio, we must also divide 4 by 2.

4/2=2

Then, multiply 3 by 5 for the width.

3*5=15

You must also multiply 2 by 5 to get the length.

2*5=10

The picture's dimensions will be 10"x15".
